SATEL-TR4+ Integration Guide, Version 1.7 4 ELECTRICAL INTERCONNECTION 4.1 DTE connector The DTE connector is a 20-pin pass-through connector. Connector is female two row 1.27 mm pitch. This connector allows the pin to enter the connector from the bottom side and protrude thru the module PCB to the top side, allowing flexible mounting heights with various pin lengths. Alternative DTE connector assembly variants available. DTE connector assembled either BOTTOM or TOP side of the module. Figure 4.
SATEL-TR4+ Integration Guide, Version 1.7 4.2 Pin order of the DTE connector Direction IN is data from DTE (Data Terminal Equipment) to the radio transceiver module. Direction OUT is data from the radio module to the DTE. The equivalent I/O schematic figures are shown in the next chapter. Pin No.

Module has detected a fault, fault codes can be read via Configuration Manager program. 4.8 VCC pins VCC pins are to feed operating voltage to the module. Limit for this voltage is mentioned in chapter 2.2 DC electrical specifications.
SATEL-TR4+ Integration Guide, Version 1.7 5 MECHANICAL CONSIDERATIONS 5.1 Fixing device to host The radio transceiver module can be mounted on to the host application by using spacers and screws. It is highly recommended to use conducting metal spacers and screws to create proper electrical conductivity between the module and the host application. Recommended materials for spacers include brass or aluminum and steel screws.
SATEL-TR4+ Integration Guide, Version 1.7 6 OPERATING MODES The radio transceiver module has the following modes of operation: MODE FUNCTION Ready to receive Search for sync from RF Receive data TX Safe mode Transmit Sleep mode Sleep1 Power mode Save Power save DESCRIPTION Module is searching for the start of a radio transmission from the RF signal. The module has found a valid radio transmission and is receiving data.
SATEL-TR4+ Integration Guide, Version 1.7 6.3 Sleep Mode When being in sleep mode, the radio part of the module is switched OFF while the serial interface communication related parts remain powered ON. The module will be automatically woken up after the CPU senses a state change in the TD1 pin. Example: The module is in Sleep1- mode. The module is woken up by sending a character or characters into the TD1 pin after which the module responses “OK”. After “OK” the module is ready for normal communication.
SATEL-TR4+ Integration Guide, Version 1.7 Transmission interval study is started over always after 100 successful sleep/wake-up cycles and, if the expected receiving slot (tRX slot) with enhanced overlap margin (toverlap) has been missed. In latter case the package is considered to be lost. toverlap = tmarg + 100 ms tRX slot, min = tmin - tmarg tRX slot, max = tmin + toverlap tTX tRX slot tmin tsleep tmarg toverlap t 0 Figure 6.1 Power save mode timing factors. E.g.
SATEL-TR4+ Integration Guide, Version 1.7 7 CHANGING PARAMETERS USING SL COMMANDS The controlling terminal device can change the configuration settings of the module. This is accomplished with the help of SL commands. SL commands can be used to change e.g. the frequency or addresses. It is also possible to ask the radio transceiver module to show current settings which are in use. 7.1 SL Commands The controlling terminal device can change the configuration settings of a radio.
SATEL-TR4+ Integration Guide, Version 1.7 The SL commands are listed in appendix 10. In order to get information of the latest and/or special SL commands please contact SATEL. 7.2 SL Command Mode The SL commands have always been enabled in the previous products like M3-R3. When the SL commands are enabled there are possibilities that the user data may start with the characters “SL” which is handled as the SL command.

SATEL-TR4+ Integration Guide, Version 1.7 9 CONSIDERATIONS 9.1 EMI Interferers The module is designed to be mounted inside a host device. The module is designed to withstand EMI even beyond type approval requirements. However, a small module which is integrated closely to modern high-speed electronics is bound to receive some interference.
SATEL-TR4+ Integration Guide, Version 1.7 9.2 Electrostatic discharge As the module is intended to be embedded in a host application, in a typical use case, the antenna port is the only port of the module directly interface with a surface or contact area subjected to Electrostatic Discharge (ESD). Thus, the antenna port is the only interface with high level ESD protection.
SATEL-TR4+ Integration Guide, Version 1.7 • • • If the channel is disturbed an external band-pass filter can be used for improving the filtering. If at the adjacent channel is TDMA, Time Domain Multiple Access, it is recommended to use time slot for receiving which is not in synchronization with the TDMA radio transmission. In Europe it is not recommended to use channels which are located near by the TETRA or television frequencies.
